This API updates the configuration of autonomous QTouch sensor with a setting that is
different from the one configured by calling touch_at_sensor_init API.
The user must populate the structure pointed by p_at_param with required settings
before calling this API.
touch_ret_t touch_at_sensor_get_config( touch_at_param_t *p_at_param )
This API retrieves the current configuration of the autonomous QTouch sensor.
touch_ret_t touch_at_get_libinfo( touch_info_t *p_touch_info)
The touch_info_t structure is filled by the library with information on the number of
autonomous QTouch channels (Fixed value of 1), number of autonomous QTouch
sensors (Fixed value of 1), number of autonomous QTouch rotors/slider (Fixed value of
0), CAT hardware version and library version.
void touch_event_dispatcher ( void )
This API needs to be called by the user application to allow the library to process the raw
acquisition data from the sensors.
Once touch_qm_sensors_start_acquisition is called, touch_event_dispatcher API needs
to be called as frequently as possible by the Host application.
The signals_callback and measure_complete_callback functions are called from the
touch_event_dispatcher API context.
